Industrial Current Transducer LEM LXS 15-NPS with LTS Footprint Compatibility and Galvanic Isolation
LXS Series Current Transducer
The LXS series are closed-loop multi-range current transducers with voltage output, designed for the electronic measurement of DC, AC, and pulsed currents. They provide galvanic separation between the primary and secondary circuits. Key advantages include very low offset drift, high dv/dt immunity, LTS footprint compatibility, and an extended measuring range for unipolar measurement. These transducers are ideal for applications such as AC variable speed and servo motor drives, static converters for DC motor drives, battery supplied applications, Uninterruptible Power Supplies (UPS), Switched Mode Power Supplies (SMPS), power supplies for welding applications, and solar inverters. They are suitable for industrial application domains.
